SMART focal plane arrays have in-pixel signal processing circuits that improve the performance of electro-optical sensors and extend their functionality. This paper describes two types of SMART focal plane array that have been developed at QinetiQ aimed at improved sensitivity and long range object identification. A novel in-pixel adaptive circuit is described which improves sensitivity by removing the background photo-signal. This allows the detector stare time to be increased resulting in lower noise bandwidth and an increase in signal-to-noise ratio. The second type of SMART focal plane array described in this paper is designed to detect time varying signals generated, for example, by helicopter blades, jet turbine engines and hot exhaust plumes. The detection of temporal signatures enables objects to be identified at significantly longer ranges than conventional focal plane arrays.
